Developed for races and short travels, the top cover reveals a wide opening, providing an easy reach to small items or energy gels.

The narrow body is designed to minimise contact with the thigh when pedalling.

Features a rain cover with Velcro attachment on top on the bag.

This top tube bag provides enough volume for the most important equipment on the small tour. There is enough space for a wallet, spare tube or mini tools. In the three small outer pockets granola bars can be accommodated, so they are quickly available without a long search. The highly resistant material is water repellent and ensures a long service life. The practical rain cover also protects the contents from heavy and prolonged rain.

The bag is attached with adjustable Velcro straps on the top and head tube.

Not a review but a doubt

Is this bag bolted onto the top tube or does it have straps?

Great top tube bag for triathlons

Easy to fit, does not shift position and has enough spaces to store gels, bars, etc... Good quality finish
